The athmosphere of Halloween for me (and it seems to others too) is what you describe as "tacky". Bright, screaming decorations, pumpkin men, Frontierland becoming Halloweenland, scary set ups for the party etc.

Well like I said I'm in the minority. I thought some of the pumpkin decorations last year were awful and very worn down.
It is a shame some people felt let down with Halloween. We enjoyed it so will be back again next year.
